To all whom it may concern:

Be it known that I, LoUIs BERTOLUS, citi- -zen of France, residing at Lyon, Rhone, France, have invented certain new and useful Improvements in or Relating to Color- Projecting Machines, of which the following is a speci cation.

The despositing of colors on textile material may be efl'ected by hand or by using a machine fitted with sprayers, the textile material to be coloured being fed past the said machine and receiving the color of colors. High class work however could notbedone hitherto by means of machines of this 1 kind'because the area over which the colors are sprayed was not sufliciently definite.

I Consequently highly finished work had to be done by hand.

The present invention has for its object i to. provide an improved apparatusby means whereof the spraying of the color is affected as accuratel as by hand and with an output which can attained by machinery only.

According to the invention, a] carriage is utilized and is suspended from a supporting track along which it travels forward and backward over the material to be 001- 3 oured. The spraying device is connected to the carriage to move therewith, and a motor is mounted on the carriage and connected with the spraying device to constantl oscillate the same about a fixed axis and through a definite angular path or stroke; the means or devices whereby this oscillating movement 85 is accomplished beng included in the essential features of the invention.

The invention also resides in the provision of an improved feeding system for the color, according to which the latter is contained in 40 a receptacle or tank secured to the carriage and is supplied therefrom by gravity to the sprayer proper where it comes in contact with the compressed air and is atomized and projected upon the work; the aforesaid sprayer having a device whereby it may be opened and closed, and the air supply pipe being equipped with a manually operated valve or the like to control the air supply and to permit the air to expand. 1

Other and further features of im rovement involved in the invention will' set forth in the course of the following detailed description of the invention and W111 be specifically recited in the appended claims.

. point of the table a.

Two constructional examples of the apparatus for carrying the invention into prac tice are illustrated in the accompanying drawings. the said; apparatus being open to modifications in details without departing from the inventiom' Figure 1 is a side elevation of the apparatus.

Figure 2 is a diagrannnatic plan view showing two of the positions into which the color-spraying means may be moved. 7

Figure 3 illustrates a second construction of the apparatus.

Referring to F i res 1 and 2, the carriage or slide is forme by a table a depending from two han ers bb fitted at their free upper ends wit rollers c and 0 respectively. The two hangers are also provided with two pivoted arms d and 03 carrying two rollers e and e respectively. The two rollers c and c are adapted to much a stationary supporting bar f, the other two rollers e and e being pressed by suitable means against the lower edge of a guiding bar 9 rigidly secured to the supporting bar f b means of the frame members It and h. l he hangers b and b are braced to each other by a crosstie z the two ends z" of which are bent at right angles to carry tensioning means and 7' to which the two ends of a chain 'are suitably secured. The said chain asses over a loosely mounted sprocket 1 an adriving sprocket m keyed to a shaft 0 which also carries a pulley p rotatedby a belt n.

The color-promoting device is mounted on the table a and comprises a tube q carrying at one of its ends the colorrojectlng means 9 to which color is supplie from containers conveniently disposed on the slide or carriage. Compressed air is supplied to the apparatus through a hose or pipe 9" secured to the other end of the tube g which is held in position by a screw 8 in a bush .5 pivoted to the end of a support 8' fixed to the table a. The latter carries an electric motor M which rotates the sprocket t keyed to a vertical stub shaft t integral with the bevel ear wheel t meshing with and driven by the vel gear wheel t keyed to the shaft of the motor. A shaft '0 fitted with a sprocket a driven through the medium of the chain :20 from the sprocket t', is rotatably mounted in a stand a fixed in os'ition at a suitable he lower end of the about the sleeve u.

shaft 4) 'projects beyond the lower face of thetablea and is fitted with a sleeve u carrying a horizontal rod'y provided with lugs, the length of which rod may bevaried by suitably manipulating the adjusting nuts 31-, The end of the rod 3 carrying the-lu is pivotally connected to the stem of a sli e 2 movably mounted on the tube The apparatus according to the invention is, operated by two separate sources of power. The first source of power, which may be of any desired kind, is adapted; to rotate the pulley ;0 through the medium of the belt n, the said pulley rotating the sprocket) m keyed to a common shaft 0. The said sprocket imparts linear motion, through the medium of the chain It, to the carriage supporting the table a; the rollers I a, 0 and e, e rolling along the supporting 'bar f and'the guiding bar 9 respectively.

The direction in which the pulley p is r0- .tated being reversible, the sprocket m causes the table a to move from left to right and conversely. Thus by, automatically or manually reversing the direction of rotation of thepulley p at the end of each travel of the slide or carriage, the table a is uniformly reciprocated over the .whole of the length of the textile. material treated.

The second source of power is preferably the electric motor M which rotatesthe sleeve u and moves the rod 3/ through the medium of the bevel gear-wheels t and t the chain :0 and'the sprocket t and v The length of the rod y may be varied by means of the nuts y, for the purpose of varying the size of the circle descrlbed by the slide a The slide 2 sliding along the tube q and moving continuously in a circle causes the said tube to be an larl reciprocated about a-fixed point, which is t e bush 8. ,Figure 2 illustrates positions taken up by the tube g owing to the revolving motion of the rod '0. The amplitude of the oscillatory movement of the nozzlecarrying end 9 of the tube q is the greater the farther the said 9 is from the centre of.

oscillation s. It is thus easy tocause the end 9 of the tube 9 to sweep. across the whole of the width of the foundation on which the color is deposited. This is obtained by suitably adjustin the length of the rod 3 and the distance. etween the end q of the tube g and the bush 8. Owing to the combinatlon of the-linear motion of the carriage'and the transverse motion of I the color-projecting means the said nozzle pands at means projecting device is operated by a motor M supported on a second tables" for example.

In this construction the color-projecting device has the following features: The hanger b is adapted to carry a manually operated valve or the like D for controlling the supply)of compressed air. The air exand is led (through the tube 9 sliding in a-bush hung by its stem 2 to the rod or arm ).to an atomizer or sprayer U of any convenient type in which the color is atomized and projected onto the work. The color is fed by gravity to the. said sprayer from a container T secured in any appropriate way to any point of the carr1age; for instance to the hanger b. The sprayer U is opened or closed by means of the rod W. The elements of this construction work in a manner substantially similar to those of the construction described with reference to Figures 1 and 2.

The mechanical and controlling elements of the constructions hereinbefore described may be combined or varied as I desired. The apparatus according to this invention yields faultless work very efli'ciently and need not be operated by skilled labour.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to vbe performed, I declare that what I claim is color-sprayin ing a supporting trac a traveling carriage suspendc therefrom; means for reciprocat ing the carriage; a spraying device connected to said carriage to move therewith; a motor mounted onthe carriage; and connections between the motor and the spraying device for constantly oscillating sald device laterally.'
